And Crux is another time giver. In October 1 Mimosa is rising heliacally to remind us summer will return, beyond the Raven there will be a new 'dawn'. Perhaps Raven stretches over 4 months (October - January), leaving twice as many months to Summer.

The limit of summer is evidently announced by the heliacal rising of Porrima (γ Virginis). The glyph number at vero in Ga5-17 can be regarded as 128 (twice 64) + 472 (twice 236) = 600 (twice 300) = 408 (twice 204) + 192 (twice 96) - see at Algol.

At Porrima the body of Virgo divides into 3 (the figure of which is like reversed ε - the Arabs wrote from right to left). Porrima is like a door from summer to winter.

... The Latins called this Porrima, or Antevorta, sometimes Postvorta, names of two ancient goddesses of prophecy, sisters and assistants of Carmenta or Carmentis, worshiped and at times invoked by their women. Porrima was known as Prorsa and Prosa by Aulus Gellius of our 2d century.

γ was specially mentioned by Kazwini as itself being Zāwiat al 'Awwā', the Angle, or Corner, of the Barker; and Al Tizini, with Ulug Beg, had much the same name for it; but Al Bīrūnī, qouting from Al Zajjāj, said 'these people are all wrong', and that 'Awwā' here meant 'Turn', referring to the turn, or bend, in the line of stars ...

... Janus was perhaps not originally double-headed: he may have borrowed this peculiarity from the Goddess herself who at the Carmentalia, the Carmenta Festival in early January, was addressed by her celebrants as 'Postvorta' and 'Antevorta' - 'she who looks both back and forward' ...

"Antevorta and Postvorta had two altars in Rome and were invoked by pregnant women as protectors against the dangers of childbirth. Antevorta was said to be present at the birth when the baby was born head-first; Postverta, when the feet of the baby came first." (Wikipedia)

Heads or tails in other words, it is a game of chance.

It is tempting to read Po-rima as a Polynesian word, possibly meaning 'good-night for summer' (it cannot mean 5 nights because this would be po e-rima). But south of the equator it could mean 'the days (po) of summer (lie ahead)', a sign of birth.

The right elbow of Virgo is Minelauva (δ):

"The medieval names Auva, Al Awwa, and Minelauva are from the Arabic,  meaning 'barking (dog)'. This star, along with β Vir (Zavijava), γ Vir (Porrima), η Vir (Zaniah) and ε Vir (Vindemiatrix), were Al Awwā, the Barker." (Wikipedia)

"On Euphrates it was Lu Lim, the Gazelle, Goat, or Stag, - or perhaps King; and, with ε, probably Mas-tab-ba, another of the seven pairs of Twin-stars of that country.

The Hindus called it Āpa, or Āpas, the Waters; and the Chinese, Tsze Seang, the Second Minister of State." (Allen)

It makes sense: The one who plays against the Sun-eyed Lion is the soft-eyed Gazelle (Lu Lim):

"Gazelle is derived from the Arabic ġazāl.The first Latin language to adopt it was Middle French, and the word entered the English language around 1600 from the French. Arab people traditionally hunted the gazelle. Appreciated for its grace, it is a symbol most commonly associated in Arabic literature with female beauty. One of the traditional themes of Arabic love poetry involves comparing the gazelle with the beloved, and linguists theorize ghazal, the word for love poetry in Arabic, is related to the word for gazelle." (Wikipedia)

But why should the 'dogs' be barking? This is still a mystery, but I can add a piece to the puzzle:

"There is, however, a remarkable variant where it is said that he [Kullervo in Kalevala] was 'sent to Esthonia to bark under the fence; he barked one year, another one, a little from the third; three years he barked at the smith of his uncle, at the wife (or servant) of the smith as his daughter-in-law' ...
